collision difficulties

[endo]

I am having difficulty understanding how to implement the collision detection for the ball in my breakout game. I have read about ray/plane and ray/polygon collision on nehe.gamedev.net (http://nehe.gamedev.net) and www.gametutorials.com (http://www.gametutorials.com) but can't see how to change it to fit a moving sphere.

Can somebody point me in the right direction please?
